Here you can find some of the most commonly asked Test Systems questions.
Q: What is the advantage of a test system from Amplicon?
A: Amplicon is a truly independent centre of expertise. We have over 40 years of experience in providing measurement & control, communication and computing solutions for our customers. Our unrivalled broad knowledge enables us to tailor the right solution for the job.
Q: What is the right computing platform for my test system?
A: This is highly dependant upon your budget and the best technical fit for your requirement. For example, a PXI platform will provide you with a compact rugged solution, whilst utilising a 19” industrial rackmount PC would be more cost effective. The processing power, environment and size limitations will usually dictate the best option for you.
Q: When I am installing a test system, what is a suitable mains supply?
A: Nearly all test systems will incorporate one or more devices which are microprocessor based. Ideally, you should connect via a good quality UPS system. A poor quality mains supply can result in performance problems and even damage. Avoid connecting direct to the same mains supply shared by noisy production equipment.
Q: What safety considerations do I need to take into account with my test system?
A: This is highly dependant upon electrical and mechanical hazards which may be encountered by the operator. In basic terms all potentially dangerous voltages should incorporate safety trips and emergency cut-off switches. Mechanical hazards need to have safety guards. Furthermore all potential hazards need to be clearly marked by appropriate warning labels.
Q: What ways do I have of developing my test software?
A: The easiest approach is to use a graphical design platform such as Agilent VEE Pro or National Instruments Labview . These software will allow you to quickly get up and running with easy to use graphical building blocks. For the more experienced software engineer, support is available for all the popular languages such as Visual Basic, Visual C++, BCB or Delphi.
Q: How do all the parts of a modern test system communicate?
A: PXI combines a conventional PCI computer Bus with the timing and triggering required with instrumentation. A PXI test system is typically in a self contained chassis and comprises of a processor module, power supply and storage. You then select modules to meet your input and output requirements.
LXI is a new technology which allows for a more distributed approach connecting various parts of test equipment together. It can be described as offering the benefits of GPIB with the flexibility of Ethernet. It is far more cost effective than GPIB and devices do not have to be in close proximity.
Both LXI and PXI have their benefits and both have their place within a modern test system.
Q: What options are available for interface panels?
A: Companies such as Mac Panel have a range of interfaces which can be attached to PXI and cPCI chassis and present an interface suitable for the Unit Under Test (UUT). If your requirement is less complicated, we can consider a more bespoke interface, or connectivity via interface cables.
